CHINA: THE WORLD'S BIGGEST SLAVE LABOR CAMP
Flashback to June 1989. Thousands of Chinese, mostly students, gathered in T- Square to protest the brutal tyranny they were being forced to live under. They were demanding that their Godless, communist government accept reforms, similar to America's constitution. They were also asking that they be allowed to speak out freely against government oppression, and not be forced to live in fear for doing so. What was the response of the Chinese government? To mercilessly and very publicly murder thousand's of their own people, many of them teenagers.
Flash forward to today. China is now the world's biggest slave labor camp, and America is their number one customer. Has anything changed in China as far as human right's are concerned? Yes. Condition's are worse in China than ever before. Anyone who offers even the slightest dissent is brutally beaten down, and the Chinese people are living in ignorance and fear. And what are America's leaders doing about it? Helping these Godless tyrants amass power and wealth on a scale unimaginable before, and selling us out while they're at it.

From 1 January 2017, changes to the Working Holiday Visa program may come into effect that will be beneficial to new working holiday makers and also those already in Australia.

Treasurer Scott Morrison has said in a media statement, the Turnbull Government recognises the important part working holiday makers play in Australia’s $43.4 billion tourism industry and are a key source of labour in industries such as agriculture, horticulture, tourism and hospitality.

The most beneficial points of change for working holiday makers will be:

Visa Application Charge reduction
Increase in the age limit
Change to work rights
Tax charges

Visa Application Charge reduction

The Visa Application Charge for a Working Holiday Visa will be reduced from $440 to $390. Saving applicants $50 AUD
Increase in Age Limit

From 1 January 2017, the age limit for a Working Holiday or Work and Holiday Visa may increase from 30 to 35 years old.
Changes to Work Rights

Currently, Working Holiday visa holders cannot work for the same employer for more than 6 months.

From 1 January 2017, a working holiday visa holder may work for the same employer for 12 months, provided the second 6 months is worked at a different premises, in a different region.
Tax Changes

The tax rate on working holiday makers earning less than $37,000 will be reduced from 32.5% to 19%. The usual tax rate will apply to those who earn above $37,000.

Employers will now need to register with the Australian Taxation Office as an employer of working holiday makers for the lower tax rate.

What was the 457 visa?
A four-year business visa which allowed people to live in Australia with their immediate family.
In 2016, the most 457s were granted to cooks, developers, programmers and medical workers

According to government statistics, 95,758 people were living in Australia on 457 visas last year, with the highest proportion coming from India (24.6%), the UK (19.5%) and China (5.8%).
I hope this helps
